B² Audio Rampage RC2

The B² Audio Rampage RC2 brings the signature B² Audio look and true subwoofer performance to RC model building. Designed specifically for 1:10 RC vehicles, this compact 2-inch subwoofer features a high-quality construction made of die-cast aluminum, a paper cone, and a foam surround. Despite its small size, it delivers surprisingly powerful bass reproduction and provides a realistic sound effect in RC cars, display models, or custom mini-audio projects. Thanks to its meticulous design, the Rampage RC2 is modeled after the larger B² Audio subwoofers—both visually and technically—and is ideal for discerning model builders.
